Acid Recovery Processes.
The traditional processes for concentrating sulphuric acid have involved the use of direct fired iron pots or steam heated falling film evaporators with silicon iron tubes. Other typical systems have used vacuum evaporating units lined with lead and acid resistant brick or have been based on submerged combustion or the direct use of combustion gases. In all cases the materials of construction used have imposed severe limitations on design and in some cases on efficiency.
In 1972, a new process was developed, the basis of which is a steam heated unit operating under vacuum. Each unit comprises a tantalum bayonet heater mounted in a natural circulation loop with a separator vessel. The design of the circulation loop was based upon extensive pilot plant work and is supported by field experience. The separator incorporates a demister to remove any entrained acid drops. The exit vapours are condensed in direct contact or surface condensers. Steam ejectors are used to extract air and maintain the desired vacuum.
The process makes extensive use of glass lined steel and tantalum to replace traditional materials. Pumps are eliminated from hot acid service by use of gravity flow systems.
The plants are custom built and usually consist of several units in series, consequently a wide range of capacities is available. In addition, there are a number of design options to suit the client's requirements. For instance, Kvaerner Chemetics unique sulphuric acid condenser may be used to obtain the relatively high vacuum required in higher strength stages. In this design, the vapours are condensed by a cooled circulation of intermediate concentration acid which is maintained at strength by adding acid from one of the higher stages and recycling a purge stream to the concentrator feed. This minimizes the loss of acid vapour to condensate, simplifies the vacuum system and makes possible the production of up to 96% H2SO4. Another example is the use of surface condensers, or direct contact condensers in an indirectly cooled closed loop, to contain any organic contaminants in a relatively small volume of condensate, thus facilitating subsequent treatment.
